About Vacuum Pumps and Vacuum Generators

Vacuum pumps and vacuum generators provide sub-atmospheric pressure for a variety of industrial and scientific applications. Different technologies of pumps are used for industrial gripping and chucking, laboratory degassing, and purification in the fields of chemical and semiconductor processing. Vacuum handling systems are used in diverse industries such as pharmaceutical, food processing, and agricultural applications.

Types of vacuum pumps include mechanical, high and ultrahigh vacuum, and venturi jet.  A variety of mechanical compression/evacuation systems are used to produce low pressures; these typically operate most efficiently in the rough or medium vacuum range.  They are frequently used as a backing or preliminary pump for high-vacuum systems.  Mechanical types include both positive and nonpositive displacement pumps.  High and ultrahigh vacuum pumps are pumps that are efficient in the molecular flow regime and require a backing pump to operate effectively.  At very low pressure or high vacuum levels, gases act like a collection of individual molecules and pump techniques that impart a preferential momentum, reduce the mean free path or trap molecules are employed.  High vacuum pumps are utilized in thin film and semiconductor fabrication processes and on many types of analytical instruments.  Venturi or fluid jet vacuum generators rely on a flow of compressed air, gas, or liquid as the "motive" fluid to pull or create a vacuum at a desired port. They contain no moving parts and require no other power than the compressed fluid.  Common configurations for vacuum pumps and vacuum generators include individual vacuum pump, combination or multi-technology pump, and vacuum pump system or station.  An integral backing pump is a high vacuum pump system that includes a mechanical, sorption, or other backing pump to provide preliminary vacuum level for the high vacuum stage of the pump.

Products & Services Related to Vacuum Pumps and Vacuum Generators

High Vacuum Pumps
High and ultrahigh vacuum pumps operate efficiently in the high vacuum region and develop molecular flow for highly evacuated systems.
Mechanical Vacuum Pumps and Systems
Mechanical vacuum pumps and systems contain devices such as pistons, claws, scrolling spirals, and diaphragms to isolate and compress air.
Regenerative Blowers
Regenerative blowers are low pressure, high volume blowers that generate centrifugal airflow.  They are used in compression, vacuum, and industrial blower applications.
Rotary Vane Vacuum Pumps and Systems
Rotary vane vacuum pumps and systems move media through the pump using a rotating assembly in the pumping chamber. Typically, there are two or more rotating vanes that move the media from inlet to outlet. Rotary vane vacuum pumps are positive displacement pumps.
Venturi Vacuum Generators
Venturi vacuum generators use the flow of motive fluid such as air, steam, or liquid to evacuate air.
